Despite recent advances in the immune mechanisms of cervical cancer (CC), the relapse still remains an actual issue and recognition of new predictive biomarkers is essential. Aim: The purpose of this retrospective study was to investigate possible differences in the primary, in situ, cellular immune response between cervical carcinoma with and without relapse. Material and Methods: Paraffin-embedded tissue samples from 61 consecutive women with CC (34 with and 27 without relapse) were immunostained for CD3, CD20 and CD45 cells. Immune cell profile densities were further assessed, assigning scores between 0 and 3: "0" meaning the absence of inflammatory infiltrate, "1+" low, "2+" intense and "3+" intense infiltrate with lymphoid follicles. Statistical analysis was performed in SPSS-13 software, p<0.05. Results: Statistically significant intra- and peri-tumoral low numbers of several immune cell subtypes are strongly associated with relapse of disease within three and five years in patients with CC (p<0.05); moreover, statistical significant correlations between immune cells and both free survival (CD3: r=0.382; CD20: r=0.404; CD45: r=0.376) and relapse (CD3: r=-0.408; CD20: r=-0.355; CD45: r=-0.354) have been demonstrated. Only CD3 was reported as predictive biomarker of relapse in CC (ANOVA, t-Student, p<0.05). Conclusions: Major differences in the cellular immune response among patients with cervical cancer with and without relapse within three and five years have been demonstrated. CD3 may be used as potential prognostic biomarkers, whereas the results are promising for adjuvant immunotherapy.
